METALLIC noon FRAME.

Application led October 5, 1922. Serial No. 592,486.

They invention relates to metallic door frames, and has for its object to provide a device of this character wherein the uprights and the head I" the frame are formed from 6 channel members which receive the adjacent sides of a door opening in a wall, whereby the frame is held against displacement. The uprights and head of the frame aie formed from angular shapedmembers i 10 having channels in the flanges which extend ,A With the above and other objects in view the invention resides in the combination and A arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in 3@ the precise embodiment of the invention may be made within the scope of what is claimed without departing Jfrom the spirit of the invention. In the drawings Y Figure l is a perspective view of the up- \per end of the door frame, parts being broken away to better show the structure.

Figure 2 is a detail sectional view through A one corner of the door in the plane of the frame.

Figure 3 is a bottom plan view of one end of the frame head.

'Figure 4 is a perspective view of the upper end of one of the frame uprights. Referring to the drawings, the numeral 1 designates the uprights of the door frame and 2 the head of the frame. The frame as a whole is made of sheet metal and finished by enameling, or in any other suitable manner. However the frame may be placed in a wall opening in any suitable manner, preferably the Jframe is placed and the wall built' around the same. The uprights 1 are formed from spaced angular shaped mem- 5- bers 3, the anges 4 of which are in parallel f ,grelation and engage theppposite sides of the wall. The angularly shaped members 3 have their flanges 5, which extend into the door opening, provided with inwardl olfset channels 6, which channels receive t e angular disposed flanges 7 of the channel member 8, which channel member is provided struck portions 10 in a parallel plane therewith for the reception of hinges, so that a door maybe easily and quickly hung in the frame.

The head 2 of the door frame is constructed 1n substantially the same manner as the upright l, and the same numerals apply thereto. The angle members 3 of the uprights l and the head 2 of the frame have miter engagement at 11, and the joint formed by the miter after' the metallic door is enameled or painted is invisible and entirely concealed. The upper end of the channel members 9, which form the door jambs are provided'with tongues 12, which tongues are received in apertures 13 when the channel sections 8 of the'u rights l and the head 2 are assembled, said) tongues bent over into the adjacent channel members 9, as shown in Figure 2 thereby holding said channel members together. By referring to Figure 1, it will be see that the channel members 9 may be assembled, after which the angled shaped members 3, which form the head 2 of the frame may be placed in position by slidin the same into position thereon, after whic the angular shaped members 3 of the uprights l may be slid upwardly into position. By forming a metallic door frame, it will be seen that the same is lire proof and that the frame may be placed in position and the brick built up around the same, or other structure, thereby obviating, especially in masonry walls, the present practice of forming a rough frame to which a trim is attached for forming a casing.

Frem the above 1t will be seen that a door frame is provided which is simple in construction, the parts reduced to a minimum andso constructed that the frame may be easily and quickly assembled, thereby reducing the cost of production to a minimum.

The invention having been set forth what is claimed as new and useful is 1. A metallic door frame comprising up;

, oppositely disposed facing rights, a header carried by said uprghts, said uprights and header bemg formed from members, said facing members 'being provlded with flanges extending towards each other, said flanges being provided with channel members disposed between the facing members and spaced apart, channeled jamb members carrled by the inner sides of the uprights and headers, said jamb members being rovided with channeled members dispose in the channels of the flanges of the facing members and longitudinally assembled therein and forming sole means for holding the same together through the outer sides of the uprights.

2. A metallic door frame comprising uprights, a header carried by said uprights and having a bevelled engagement with the upper ends of the upri hts, said uprights and header being forme from oppositely disposed spaced facing members, inwardly eX# tending flanges carried by the facing members, channels carried by said flanges, jamb members carried by the inner sides of the upri hts and header, and spaced chaneled mem ers carried by the jamb members and disposed inthe channel members of the fac` ing flanges and longitudinally assembled o therein and forming sole means for securing the facing members together through the header. l 3. A metallic door frame comprising uprights, a header carried bv said uprights and having a bevelled engagement with the 36 =upper ends thereof, said uprights and header being formed from spaced facingand pos1tioned through the outer sides ofV the uprights and interengaging means between the upper ends of the jamb members carried by the uprights and the j amb -member carried by the header in spaced relation to the ends of said last named jamb member.

In testimony whereof we aix our signatures.
